  1. Crushed hell creek therapod

    Hey y'all. I've had this therapod tooth for a while, and I'm wondering if an id can be placed on it. It's completely shattered unfortunately, so I don't expect an id to be easy. It's from the Hell Creek formation. It was labeled as T. rex, but I'm not convinced. Though, I've very little knowledge of dinosaur teeth. I've attached various photos of the tooth in question, and some reference serrations from a probable rex. Thank you!
  2. Partial T.rex tooth or Nanotyrannus?

    I bought this tooth last week, and it arrived today. I’m really excited about it, because it’s my biggest tyrannosaur tooth so far, and I believe it’s T.rex. It was found in the Hell Creek formation, but no other locality is given. I think it’s T-rex because of the base lacking any pinching, and the overall robustness, but I always like to hear any opinions others have. Thanks!
  3. Last year's Hell Creek finds

    Here are some of the better finds from my digging trip in South Dakota last year. First up is what is likely an osteoderm from Ankylosaurus. This specimen is gone for research. I've got a "stupid rookie" story to go along with this if anyone is interested. Next is a section of Edmontosaurus rib with the head and part of the main. This still needs final cleaning and consolidation. I'm still debating whether to leave them separate or re-create the missing portion and join them. This is the largest and most complete ossified Edmontosaurus tail tendon I have seen. Most of the time you only find little 1 inch sections. This one is completed prep, retaining some of the matrix and a random BOB, as dug. Nice chunk of turtle shell. I have a love/hate relationship with these. This is one is large and quite thick. Most of them are extremely thin and fragile as egg shell. Still needs final prep and consolidation. Unfortunately its a covered in CA, which is making it so much harder. A very nice Tricerotops tooth that my son recovered. He is like a magnet for these large trike teeth. This is the 3rd big one he's found. All I find are tiny spitters. This is a juvenile T-Rex tooth, found beside the Ed rib. This one is gone for research. There's also a small nano-T tooth missing its tip, and a large BOB which I think could be a bit of Trike frill. No pics of those available at this moment. I'll have to add them later.
  4. Fibula ID please

    Hello, I recently finishing preparing this fossil and you may have seen it in the Prep section, however given I would also appreciate an ID, the smart suggestion was made to move it here. I bought this off Ryan at Hell Creek Dinosaurs who discovered it on one of his trips last summer to Hell Creek. Apologies for not having it next to a scale, but it's 46cm long. Ryan suggested it could be a Triceratops or a Hardosaur (Edmontosaurus one assumes) and although I was erring on the latter, will admit having seen some trike fibulas recently, now I'm not 100% sure, hence this post. Showing pics from the find (Ryan very kindly agreed I could use. Thanks again!) and now after prep. If these aren't clear enough or you need more to be able to help, just let me know. Any thoughts much appreciated. Thanks Dave ps: If you're questioning the prep, in my defence, it was my first ever...
  5. My first bone prep...

    Hey, Others viewing this section regularly will see my current project is a mosasaur skull, I have however been splitting my time between this and finishing my last (first real) prep project which has been dragging a little; this fibula. I bought this off a top chap (Ryan at Hell Creek Dinosaurs) who discovered it on one of his trips last summer, but decided it wasn't one for his collection. It was covered in a horrible chalk/clay coating which (as Ryan predicted) was the stuff of nightmares to get off. That said, with dark nights and miserable weather in the UK, time was something I have had on my side recently, so three months later, here's the finished item. In reality, it's been finished for a while, but I only got round to making the display stand yesterday and wanted to show the finished project. It's about 50cm long and comes from the Hell Creek formation. Ryan suggested it could be a Triceratops or a Hardosaur (Edmontosaurus one assumes) and although I'm erring on the latter, will admit I'm not 100% sure, so please let me know if you have a clearer opinion! Given this is my first 'real' prep job, would love to know thoughts and/or improvements I could make - It came in six sections, they were cleaned using a variety of tools (engraver, Dremel, dentist pics and various other hand tools/abrasives). End of each section stabilised and strengthened with CA, glued together with epoxy and finally coated in PVB to protect. Showing pics from find (Ryan very kindly agreed I could use. Sir, if you're a member of this forum and happen to see this, thanks again!) all the way through to now (as at yesterday in fact) Cheers Dave
  6. Hell Creek Turtle Beak

    Here's an interesting fossil I found from the summer which I am just getting around to posting. I believe it's a piece of turtle beak based on its shape and the numerous holes which I believe are part of the vascular structure of the beak, rather than just the standard cancellous tissue of bone. Here's a modern one I found online for comparison. And one from a marine turtle on the Oceans of Kansas website.
  7. Hell Creek Oddity

    I found this bone over the summer in the Hell Creek formation of South Dakota. I have no idea what it could be, and I don't even know if it's complete. It's slightly reminiscent of the ear bones I see on here sometimes, but that's just a guess. The fossil is about a centimeter from top to bottom and around 8 mm wide
  8. Hell Creek Femur

    Hi I recently stumbled upon this femur with with a very large & pointy fourth trochanter. I have not seen that before. The length is 45cm. Sorry for not providing straight views. Location: Hell Creek Fm, Jordan, Montana Do you know what animal it belongs to?
  9. Dakotaraptor? Or nanotyrannus?

    This next tooth i just recently purchased was sold to me as a probable dakotaraptor tooth. Its from the hell creek formation in Powder River Co. MT. Its CH is 18 1/2 mm....posterior serrations are 20 per 5 mm. Anterior serrations are 25 per 5 mm. @Troodon , @Andy, @fossilsonwheels
  10. Paleocene Dinosaurs

    So I was looking through some “older” papers and found this one by Rigby et al. (1987)(pdf attached). They were looking at some of the rock formations specifically members of the Hell Creek Formation. In one area, they have a lot of river deposits from before and after the K-T boundary. In one of the river deposits from the Paleocene as dated by pollen fossils, contains ungulate mammal fossils and some dinosaur teeth specifically ceratopsian and theropod teeth as far as I understood. They recognize that the dinosaur fossils could have been eroded from the bank and fallen in but the fossils aren’t weathered like they should have been and the river wasn’t the right kind that would rework sediments. I’m not sure I believe their arguments but what do you guys think? Rigby-et-al_1987_Paleocene-dinos.pdf
  11. Dakotaraptor steini ?

    This next tooth was listed as a possible dakotaraptor steini...what do you guys think? Sorry for the finger placement in some of the pictures.....from the hell creek formation in powder river co. , MT. The size is 15/16 " and Serrations on the posterior of the tooth are 5 per mm and 10 per 2 mm. The anterior serrations look smaller and look to be about 6 per mm.... @Troodon
  12. Tyrannosaurus rex or nanotyrannus

    Hey everyone....im gonna start posting everything i have over the next few weeks to get everyones opinions.....if i need to post more info about a specimen just let me know.....first up is a tooth tip i got ...it was labled t- rex or nanotyrannus......from hell creek.
  13. Fort Peck Lake

    Is it legal for a person to search for fossils in and around the state parks located on Fort Peck Lake? Can a person take a boat and hunt for fossils in some of the more remote regions of the lake? It's technically the Missouri River, so as long as you don't go above the high water mark you're not trespassing as far as I know. In the book "Rise and Fall of the Dinosaurs" the author said you can find several T Rex teeth in a day just walking around the Hell Creek formation.
  14. Help on Claw ID

    Hello everyone, I found this nice claw in South Dakota over the summer and have yet to find a definitive match for its identity. It's about a centimeter and a half long.
  15. What Kind of Premax?

    I found this theropod premaxillary tooth on my last day in North Dakota this past summer and since then I've wondered about what it is and if it had and diagnostic features of an particular theropod group. It's just over a centimeter long and has no serrations.
  16. Struthiomimus Vertebrae

    Hi all, these two fossils were found in North Dakota's Hell Creek fm. this past summer. I believe they are vertebrae from ornithomimosaurs but I'm not certain. I'd like the input of my peers on the forum. The first one seems like it would be from a juvenile as it's mostly complete but very small at just under an inch long. The other is missing an end, but is a bit larger at about an inch and a quarter in length. First: Second:
  17. Hell Creek Fish (?) Jaw Section

    Hey everyone, I found this little jaw section at a microsite in North Dakota's Hell Creek formation this past summer and I'm finally getting around to posting about it. I believe it's fish, possibly gar, but I'm not sure. I'd like to know people's opinions. It's about 1.3 centimeters long. Thanks, Noel
  18. Tyrannosaur Tooth ID

    Hi Fossil Forum, I’m hoping you could help me with a tooth ID. It’s from Hell Creek and I believe a Tyrannosaur. I’d love for it to be a T. Rex, but I’m hoping you could confirm either way. Thanks! Also, this is my first post, so if it’s in the wrong discussion, just let me know and I’ll delete and re-post.
  19. Just opened the package up with this beauty in it. I have wanted a T-rex tooth for a long long while but I have never been in a position where I was willing to spend the money for the size I would get. Anyway, after watching them go up in price for the last decade plus, I finally bought one. Sold a nice old winchester rifle to pay for it, but I am pleased as punch with it. It is a hair over 3 inches in length. Found in Hell Creek formation in Powder river county, Montana. Tooth was originally in 4 pieces and has been glued back together. It's got some wear and missing enamel, but personally I think it makes it better. The serrations are amazing.
  20. Because it was the first time for me to see some teeth from the Hell Creek Form. in Montana here in Germany at our local fair (and I am quite at the beginning with my collection of dino teeth) I purchased the following teeth. According to the seller both are from the "Hell Creek Form., Badlands, Carter County, Montana". The first tooth is labeled as "Thescelosaurus garbanii". Is this correct and how can the teeth of T. garbanii and T. neglectus be distinguished?
  21. Dromeosaur or Tyrannosaur?

    I was reading some posts about tooth ID last night on the forum. I read that dromeosaur teeth from the Hell Creek formation have different serrations on the front and the back. If I remember correctly, I think I saw a post that said the back side of the tooth have larger serrations. I saw this tooth from Carter county Montana this morning, listed as dromeosaur but to me it looked like both sets of serrations were pretty uniform. I was wondering if there’s a chance this is a tyrannosaur tooth, or if it is some type of dromeosaur tooth. It’s approx. 3/8 long, so maybe the size alone is enough to rule out tyrannosaur but I thought I might as well check. Unfortunately only 2 pictures were given.
  22. Hell Creek dinosaur toe bone?

    I picked up a little Hell Creek lot that hat this fossilized bone in it. I think it might be a theropod toe bone from looking around on the web at Hell Creek bones. Anyone with more experience (most everyone) have any opinions?
  23. Hell Creek Croc Bone??

    I am trying to organize some of the fossils that I recently picked up at the Garage Sale that I visited the last few weeks. I have this piece that was among a lot of turtle shell and small random Dino bone pieces, nothing that would be identifiable that was collected in the Cretaceous of Buffalo, South Dakota. I am thinking that this piece might be crocodile, what do you think? @jpc
